I recently purchased the Weider Ultimate Toning Wheel. I have mixed feelings on this product.
What I like: Simple, easy to use, inexpensive, does a pretty good job of toning abdominals, shoulders, chest, and arm muscles, the price ($9.99), the portablility, and the ease of putting together and taking apart.
What I don't like: I guess there is basically only one real thing I don't like about this product. That is that the wheel itself seems to be made of a very lightweight plastic. I expected it to feel heavier - more like a tire. I guess for $9.99 one shouldn't epect premium quality, though. This really isn't a major issue.
When I was a child, my mother had something similar to this. It was constructed with more of an actual tire for a wheel. I was expecting the same product. I guess things change over the years.
Overall, I would recommend this for an expensive way to tone specific muscle groups .
